IMPROVEMENT IN COMBINED STOVE-PIPE SHELVES AND DRUMS.

Specification forming part of Letters Patent No. 140,454, dated July 1,1873; application filed March 25, 1873.

To all whom it may concern:

Be it known that I, THOMAS BLADON, of Oak Harbor, in the county ofOttawa and in the State of Ohio, have invented certain new and usefulImprovements in Combined Stove- Pipe Shelves and Drums; and do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing making a partof this specification, in which Figure 1 is a perspective view of mydevice as arranged for use upon a stove. Fig. 2 is a vertical centralsection of the same, and Fig. 3 is a plan view of its upper end with thecover removed.

Letters of like name and kind refer to like parts in each of thefigures.

The objects of my invention are to enable a larger proportion of theheat escaping from a cooking-stove to be utilized, to furnish aconvenient means for sustaining small cooking-utensils, and for keepingtheir contents warm, and to enable the odors of cooking food to becarried into the exit-flue of the stove; to which end it consistsprincipally in the means employed for causing the odors of or from thecooking food to pass into the exitflue, substantially as and for thepurpose hereinafter shown. It consists, further, in the combinedstove-pipe shelf, heating-drum, and ventilator as a whole, when itsseveral parts are constructed and arranged to operate substantially asand for the purpose shown.

In the annexed drawing, A represents the exterior casing or wall of thedrum, having a conical form, and inclosed at its larger upper end bymeans of a cover, B. Within the interior of the cone A is placed asecond cone, 0, which has a considerable less size than the former, isopen at its ends, and is attached to the same by means of three or morewings, D, which extend radially between said parts, and secure said cone(J in position equidistant from the sides and ends of said outer cone.

Passing through the center of the cover B is a pipe, E, which extendsdownward and terminates about midway between the upper and lower ends ofthe inner cone.- A short pipe or collar, F, is attached to the lower endof the outer cone, and in connection with said upper pipe furnishes ameans whereby the device may be connected with and caused to form a partof the stove-pipe. A butter fly damper, G, pivoted within the lower endof the inner cone 0, completes this portion of the device, the upper endof which forms a convenient shelf for the reception of smallcooking-utensils, while the heat of the escaping gaseous products ofcombustion is imparted to said utensils and their contents in thefollowing manner:

When the damper G is opened the escaping gases pass directly through thelower end of the inner cone, and into and through the pipe E 5 but whensaid damper is closed said gases are compelled to flow outward aroundthe exterior of said inner cone, upward over its upper end, and thencedownward to and into the lower end of said pipe E, having during suchpassage given off a large percentage of their heat to the outer cone andits cover.

In order that the odors from the cooking food may be caused to pass intothe exit-flue, a number of openings, h, are formed in and through theupper end of the front side of the cone A, and, when desired, areinclosed by means of a sliding damper, H.

A hood or ledge, I, secured to or upon said cone immediately above saidopenings, and

from thence extending forward and slightly downward, in'a measureprevents the current of air from passing upward, and directs it into thesame.

For convenience, the hood I may be made detachable, and removed whendesired.

The device is now complete, and furnishes a simple, cheap, and usefuladdition to a cooking-stove, by means of which the capacity andconvenience of the latter are materially increased.

Having thus fully set forth the nature and merits of my invention, whatI claim as new 1s-= 1. In combination with the drum shown,
